Allen was called up because of injuries to No. 1 goaltender Jaroslav Halak. He was then given the chance to play when the Blues' other goalie, Brian Elliott, was struggling mightily and the team was mired in a nasty funk. Coach Ken Hitchcock turned to Allen eight days ago, and he was just what the doctor ordered. St. Louis went 3-0-0 on a road trip, including a shootout win in Vancouver.

But Halak is healthy again and, considering Halak and Elliott were the league's best duo last season -- and are both paid pretty well -- Allen was the odd man out. So instead of keeping three goalies on the roster, the Blues instead sent Allen down to Peoria.

It's a pretty safe bet to say this isn't the last that we'll see of Allen. He showed he's a good goaltending prospect; he had a 2.62 goals against average and went 3-1-0. The save percentage wasn't exactly pretty at .895, but there is no doubting he was huge when they needed him.
